ADJ USTABLE RABBET-STRIP.

SPECIFICATION forming part of Letters Patent No. 642,678, dated February 6, 1900.

Application filed March 4, 1899.

To all whom it may concern.-

Be it known that I, SAMUEL S. COLT, a citizen of the United States, residing at Orange, in the county of Essex and State of New J ersey, haveinvented certain new and useful Improvements in Adjustable Rabbet-Strips; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part ofthis specification.

My present invention has reference to improvements in doors and door-jambs and the invention has for its primary object to pro vide a simple arrangement of rabbet-strip which is adjustable in relation to the doorjamb and the door-casing, whereby the several parts may be properly adjusted to take up any shrinkage of the wood, and, furthermore, to prevent the admission of cold air, wind, 850., through the enlarged crevice formed between the stile of the door and the rabbet-strip, the arrangement of the parts being such that the rabbet may be enlarged or made smaller, according to the varying conditions that may present themselves.

The invention therefore consists in the novel construction of adjustable rabbet-st-rip hereinafter set forth and in the several novel arrangements and combinations of the parts and operating mechanism connected therewith, all of which will be more fully described in the accompanying specification, and finally embodied in the clauses of the claim.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a horizontal section of a portion of a door-casing, blocking, door-jamb, and adjustable rabbet-strip, illustrating one arrangement of operating mechanism for adjustably securing the rabbet-strip in its operative position. Fig. 2 is a Vertical crosssection ofv the same, taken on lineac in said Fig. 1, looking in the direction of the arrow m. Fig. 3 is a horizontal section of the parts represented in said Fig. 1, but illustrating a slightly-modified arrangement of the adj ustable rabbet-strip. Fig. 4: is a top view of a bushing employed with my invention.

Serial No. 707,729. (No model.)

Similar letters of reference are employed in the said above-described views to indicate corresponding parts.

In said drawings, a indicates the stationary framework; b, the blocking; c, the door-casing, and d the door-jamb. The door-casing is secured to the framework a by means of suitable nails 0 or in any other suitable manner.

The rabbet-strip is indicated by the reference-letter cl and is preferably held in position by suitable nails 0 of wire, so as to bend when the strip 01 is to be adjusted in the manner to be hereinafter fully set forth without breaking the nails or without straining the wood. Said nails 0 are driven into and through the casing at an angle, each nail being set so that its pointed end will strike a Vertically-arranged groove d in the strip (1, whereby the nail will enter said strip without glancing off, as might be the case where said groove 01 is dispensed with. Secured to the said rabbet-strip d by means of nails d or in any other well-known manner is a molding d which is formed with an offset d projecting over the edge 0 of the casing c, the same being slidably arranged in relation thereto to fully cover the open joint formed between said molding and the edge of the door-casing.

The door is indicated by the reference-letter g, and d is a stop-bead which is sometimes used when the surface d of the doorjamb d and the surface d of the strip (1 are placed flush with each other, as indicated in Fig. 1, but which is usually dispensed with when the strip (1 and the door-jamb d are arranged, as indicated in Fig. 3, to form the rabbet.

The mechanism for moving or adjusting the rabbet-strip d in the directions indicated by the arrows 1 and 2 in Figs. 1 and 3 consists, essentially, of an arrangement of hinge-plates e, usually four in number, but this may be departed from, which are provided with perforated ears or lugs e and are secured to the inner surface of the door-jamb d in suitable positions, as may be necessary under varying conditions, by means of screws 6 In the said ears or lugs e of each plate e I have arranged a pine on which is hinged the perforated end a of certain levers or arms 6 each lever or arm having a perforated end portion 6 whereby it can be secured in proper position by means of a screw or screws 6 to the back of the adjustable rabbet-strip d, substantially as illustrated. In order to prevent the sagging of the strip (1', I may secure beneath each lever or arm 6 against the back of the door-jamb d, by means of a screw e or in any other suitable manner a plate e which is provided with a supporting-shoulder e on which said lever rides and is supported, as will be clearly understood. To move the said strip (1 in or out to increase or decrease the size of the rabbet, I have secured to the framework a in any well-known manner a bracket a, which has a post a and a pair of perforated lugs a forming a bearing for a pin a. On said pin I have arranged, so as to oscillate thereon, an arm a, the one end of which is bifurcated, as at a, and the other end of which has a screw-threaded hole CH. The lugs or cars forming the bifurcated end a of said arm a are perforated and have secured in the perforations a pin a with which is pivotally connected the perforated end f" of a rod f, the other end of which is operatively secured to the rabbetstrip cl by means of screws f or in any other well-known manner.

Secured in an opening in the door-jamb d is a bushing 72., provided with a flange 72 and a screw-threaded end h onto which a nut it can be screwed for securing said bushing in position in the door-jamb, substantially in the manner illustrated in Fig. 1. Said bushing it is provided with a cone-shaped part h", a tubular duct h, and an opening it in the one side thereof. A central opening 7L7 is formed above said cone-shaped part 7L the sides thereof inclining inwardly to form an annular shoulder h Rotatively arranged in said eone-shaped portion 7& is the head i of a screw-bolt 'i, the same being operatively held therein by means of said flange or shoulder 72 and a suitably-formed block 729, which is placed in the opening 72. to close the same after the screw-bolt has been passed through said opening and arranged in the said bushing, as stated and as clearly illustrated. The said screw-bolt i extends from the rear of said bushing h and has its screw-threaded end 2' operatively connected with the screw-threaded hole a of the arm a. It will thus be seen that when the head i of the bolt 2' is turned by means of a screw-driver or other tool the intermediately-arranged arm a and rod f, connected therewith, will cause the rabbetstrip d to be moved accordingly, whereby in case of the shrinkage of the parts of the door or the casing the enlarged crevice thus formed can be easily reduced to prevent the admission of air and wind. At the same time the molding 01 which is secured to the rabbetstrip 61, will have its projecting portion d moving over the edge e of the casing c, whereby the joint between said parts will remain covered.

In some cases the strip d may be arranged as indicated in Fig. 3, whereby the stop-piece d (shown in Fig. 1) is dispensed with.

The many advantages of my present invention and the simplicity as well as the operativeness of the present construction will be evident from the above description and an inspection of the drawings.

I am fullyaware that changes may be made in the several arrangements and combinations'of the parts, as well as in the details of the construction of the same, without departing from the scope of my present invention. Hence I do not limit my invention to the exact arrangements and combinations of the parts as herein described and illustrated, nor do I limit myself to the precise details of the construction thereof.

Of course it will be understood that I may use any desirable number of hinge-plates e and levers connected therewith and that I may use any number of operating mechanisms for adjusting the rabbet-strip d. In some instances I may employ but one operating mechanism with each door-jamb and rabbetstrip; but in other instances I employ two or more sets of mechanism for adjusting the rabbet-strip. It will also be evident that the door may be hung directly to the adjustablerabbet-strip, whereby when the latter is adjusted both the said strip and door will be moved together in a direction toward the rabbet-strip on the opposite side of the door-casing, whereby the edge of the door and the rabbet-strip and door-jamb on said side will produce the proper joint to prevent the admission of cold and wind, as will be clearly understood.

Having thus described my invention, what I claim is 1. The combination, with the stationary frame, door-casing and door-jamb, of a rabbet-strip slidably connected with said doorjamb, and mechanism connected with said stationary frame, door-jamb and strip, for adjusting the said strip, substantially as and for the purposes set forth.

2. The combination, with the stationary frame, door-casing and door-jamb, of a rabbet-strip slidably connected with said doorjamb, and mechanism connected with said stationary frame, door-jamb and strip, for adjusting the said strip, consisting, essentially, of a support secured to said stationary frame, a lever pivotally arranged in said support, an adj usting-screw rotatively arranged in a bushing in said doorjamb, and operatively connected at its one end with one end of said lever, and a connecting-rod between the other end of said lever and said rabbetstrip, substantially as and for the purposes set forth.

3. The combination, with the stationary frame, a door-casing 0, having an edge 0 and a door-jamb, of a rabbet-strip slidably connected with said door-jamb, and adjustable, a molding (1 having an offset (1 projecting over said edge and in slidable arrangement therewith, and mechanism connected with v said stationary frame, door-jamb, and strip a door-jamb, of a rabbet-strip slidablyconnected with said door-jamb, and adjustable, a molding 01 having an offset (1 projecting over said edge 0 and in slidable arrangement therewith, and mechanism connected with said stationary frame, door-jamb, and strip for adjusting the said strip, consisting, essentially, of a support secured to said stationary frame, a lever pivotally arranged in said support, an adj usting-screw rotatively arranged in a bushing in said door-jamb, and operatively connected at its one end with one end of said lever, and a connecting-rod between the other end of said lever and said rabbetstrip, substantially as and for the purposes set forth.

5. The combination, with the stationary frame, a door-casing c, and a door-jamb, of a rabbet-strip connected with said door-jamb, having a groove d and nails 0 in said casing, arranged and entering said groove in the rabbet-strip, substantially as and for the purposes set forth.

6. The combination, With the stationary frame, a door-casing c, and a door-jamb, of a rabbet-strip connected with said door-jamb, having a groove d nails 0 in said casing, arranged and entering said groove in the rabbet-strip, and mechanism connected with said stationary frame, door-jamb, and strip for adjusting said strip, substantially as and for the purposes set forth.

7. The combination, with the stationary frame, a door-casing c, and a door-jamb, of a rabbet-strip connected with said door-jamb, having a groove d nails 0 in said casing, arranged and entering said groove in the rabbet-strip, and mechanism connected with said stationary frame, door-jamb, and strip for adjusting said strip, consisting, essentially, of a support secured to said stationary frame, a lever pivotally arranged in said support, an adj usting-screw rotativel y arranged in a bushing in said door-jamb, and operatively connected at its one end with one end of said lever, and a connecting-rod between the other end of said lever and said rabbet-strip, substantially as and for the purposes set forth.

In testimony that I claim the invention set forth above I have hereunto set my hand this 1st day of March, 1899.
